Carbon-monoxide testing during a home inspection

Although much of this article appeared in Summit Homes & Properties last year, we feel so strongly about carbon-monoxide testing during home inspections that we felt it important to repeat the advice. Trimming expenses is something that we can all do to help our bottom lines during these stricter economic times, but eliminating a home inspection that tests for carbon monoxide is not a place to cut corners. A home inspection can uncover unseen dangers including carbon-monoxide leaks, natural-gas leaks, malfunctioning heating systems or electrical systems in need of repair. For today, we will focus on the unseen dangers of carbon-monoxide poisoning.

Carbon monoxide is a colorless, odorless, tasteless, toxic gas formed by the incomplete oxidation of carbon in combustion. Sources are varied: furnaces, gas-water heaters, wood stoves, fireplaces, gas stoves, generators and other gasoline powered equipment, vehicle exhaust from attached garages, unvented kerosene and gas-space heaters, and tobacco smoke. Some sources cause high concentrations of CO in an indoor air supply. Worn or poorly adjusted or maintained combustion devices like boilers or furnaces can be significant sources of lower concentrations. Annual check-up and maintenance could eliminate this.

Symptoms of exposure to low levels of CO include headaches, dizziness, nausea, and fatigue. At higher concentrations, impaired vision, coordination, and reduced brain function can occur. High concentrations of CO exposure can be fatal.

Steps to reduce carbon monoxide include annual check-up and maintenance of boilers and furnaces, open flues when a fireplace is in use, eliminate the idling of vehicles inside garages, and keeping gas appliances and fireplaces properly adjusted. Your home needs maintenance just like your car needs a tune-up. Scheduling an annual heating system inspection by a qualified specialist is particularly important in Central California where our climate keeps furnaces and boilers all winter.

As a routine part of the home inspection process, your home inspector should test for carbon monoxide gas. Talk to your inspector about the appliances in your home that can produce carbon monoxide. The more you educate yourself, the safer you and your family will be. Finally, once you’ve closed on your home, visit one of the local hardware stores that sell carbon-monoxide alarms. After your home inspector initially tests for gas leaks, installing a carbon-monoxide alarm is a wise investment and will help to keep you and your family safe from this dangerous gas.
